I planted some marigolds, and I love them. But, I was wondering if you all could suggest flowers that are as robust, but had the size, and fragrant? I'm looking for something that is inexpensive, that I can buy bulk seeds of, self propagating.Color, of course us a major factor. I like reds, yellows, and blue..

I live in tropical environment, plenty of rain, followed by few days if sun. Soil..bad.

Blessings.
